Knurling technique for non-woven paper

Abstract

The invention discloses a knurling technique for non-woven paper, which comprises the following steps: 1, drying the non-woven paper at 140-180 DEG C till the non-woven paper is dry; 2, atomizing the surface of the non-woven paper; 3, performing hot-pressing treatment, wherein the hot-pressing temperature is at 150-200 DEG C, the speed is at 10-15m / min and the required pressure is between 5 and 8 kilograms; 4, drying and rolling. According to the knurling technique for the non-woven paper, the knurling efficiency can be greatly increased during a production process while the knurling quality of the acquired non-woven paper is high.

Description

[0001] technical field [0002] [0003] The invention relates to an embossing process, in particular to an embossing process for non-woven paper. [0004] Background technique [0005] [0006] Non-woven paper is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. . To put it simply: it is not interwoven and knit together by yarns one by one, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes , you will find that it is impossible to extract the thread ends one by one. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. [0007] However, the current non-woven pap...

Problems solved by technology

[0007] However, the current non-woven paper cannot be completely embossed. Generally, cold pressing is used for embossing. However, the embossing process is complicated, and the resulting embossing effect is very unsatisfactory. It is easy to lose shape, and the lines and patterns are not clear.
